-[![Buy me a coffee](https://www.buymeacoffee.com/assets/img/custom_images/orange_img.png)](https://buymeacoff.ee/n1try)
+If you like this project, please consider supporting it 🙂. You can donate either through [buying me a coffee](https://buymeacoff.ee/n1try) or becoming a GitHub sponsor. Every little donation is highly appreciated and boosts the developers' motivation to keep improving Wakapi!
+
+## Demo 
+🔥 **New:** There is hosted [demo version](https://apps.muetsch.io/wakapi) available now. Go check it out! Please use responsibly.
+
+To use the demo version set `api_url = https://apps.muetsch.io/wakapi/api/heartbeat`. However, this hosted instance might be taken down again in the future, so you might potentially lose your data ❕
 
 ## Prerequisites
-### Server
+**On the server side:**
 * Go >= 1.13 (with `$GOPATH` properly set)
-* An SQL database (MySQL or Postgres)
+* gcc (to compile [go-sqlite3](https://github.com/mattn/go-sqlite3))
+    * Fedora / RHEL: `dnf install @development-tools`
+    * Ubuntu / Debian: `apt install build-essential`
+    * Windows: See [here](https://github.com/mattn/go-sqlite3/issues/214#issuecomment-253216476)
+* _Optional_: A MySQL- or Postgres database
 
-### Client
+**On your local machine:**
 * [WakaTime plugin](https://wakatime.com/plugins) for your editor / IDE
 
-## Usage
-* Create an empty database 
-* Enable Go module support: `export GO111MODULE=on`
-* Get code: `go get github.com/muety/wakapi`
-* Go to project root: `cd "$GOPATH/src/github.com/muety/wakapi"`
-* Copy `.env.example` to `.env` and set database credentials
-* Set target port in `config.ini`
-* Build executable: `go build`
-* Run server: `./wakapi`
-* Edit your local `~/.wakatime.cfg` file
-  * `api_url = https://your.server:someport/api/heartbeat`
-  * `api_key = the_api_key_printed_to_the_console_after_starting_the_server`
-* Open [http://localhost:3000](http://localhost:3000) in your browser
+## Server Setup
+### Run from source
+1. Clone the project
+1. Copy `.env.example` to `.env` and set database credentials
+1. Adapt `config.ini` to your needs
+1. Build executable: `GO111MODULE=on go build`
+1. Run server: `./wakapi`
 
-**As an alternative** to building from source or using `go get` you can also download one of the existing [pre-compiled binaries](https://github.com/muety/wakapi/releases).
+**As an alternative** to building from source you can also grab a pre-built [release](https://github.com/muety/wakapi/releases). Steps 2, 3 and 5 apply analogously.
+
+**Note:** By default, the application is running in dev mode. However, it is recommended to set `ENV=production` in `.env` for enhanced performance and security. To still be able to log in when using production mode, you either have to run Wakapi behind a reverse proxy, that enables for HTTPS encryption (see [best practices](i#best-practices)) or set `insecure_cookies = true` in `config.ini`. 
 
 ### Run with Docker
-* Edit `docker-compose.yml` file and change passwords for the DB
-* Build the container `docker-compose build`
-* Start the application `docker-compose up -d`
-* To get the api key look in the logs `docker-compose logs | grep "API key"`
-* The application should now be running on `localhost:3000`
+```
+docker run -d -p 3000:3000 --name wakapi n1try/wakapi
+```
 
-### User Accounts
-* When starting wakapi for the first time, a default user _**admin**_ with password _**admin**_ is created. The corresponding API key is printed to the console.
-* Additional users, at the moment, can be added only via SQL statements on your database, like this:
-    * Connect to your database server: `mysql -u yourusername -p -H your.hostname` (alternatively use GUI tools like _MySQL Workbench_)
-    * Select your database: `USE yourdatabasename;`
-    * Add the new user: `INSERT INTO users (id, password, api_key) VALUES ('your_nickname', MD5('your_password'), '728f084c-85e0-41de-aa2a-b6cc871200c1');` (the latter value should be a random [UUIDv4](https://tools.ietf.org/html/rfc4122), as can be found in your `~/.wakatime.cfg`)
+By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see [Dockerfile](https://github.com/muety/wakapi/blob/master/Dockerfile) and [.env.example](https://github.com/muety/wakapi/blob/master/.env.example) for further options.
+
+## Client Setup
+Wakapi relies on the open-source [WakaTime](https://github.com/wakatime/wakatime) client tools. In order to collect statistics to Wakapi, you need to set them up.
+
+1. **Set up WakaTime** for your specific IDE or editor. Please refer to the respective [plugin guide](https://wakatime.com/plugins)
+2. Make your local WakaTime client talk to Wakapi by **editing your local `~/.wakatime.cfg`** file as follows
+
+```
+api_url = https://your.server:someport/api/heartbeat`
+api_key = the_api_key_printed_to_the_console_after_starting_the_server`
+```
+
+You can view your API Key after logging in to the web interface.
+
+## Customization
 
 ### Aliases
 There is an option to add aliases for project names, editors, operating systems and languages. For instance, if you want to map two projects – `myapp-frontend` and `myapp-backend` – two a common project name – `myapp-web` – in your statistics, you can add project aliases.
 
-At the moment, this can only be done via raw database queries. See [_User Accounts_](#user-accounts) section above on how to do such.
-For the above example, you would need to add two aliases, like this:
+At the moment, this can only be done via raw database queries. For the above example, you would need to add two aliases, like this:
 
-* `INSERT INTO aliases (type, user_id, key, value) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend')` (analogously for `myapp-backend`)
+```sql
+INSERT INTO aliases (`type`, `user_id`, `key`, `value`) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend');
